IMPROVEMENT IN WIND-WH EELS.

Specication forming part of Letters Patent No. 52,33. dated February G,1866.

To all whom it may concern:

Be it known that we, BENJ. F. BURNETT and Tir-IOS. VANDEVORT, of Phelps,in the county of Ontario and State of New York, have invented a new andImproved Mode of Constructing Wind-Wheels; and we do hereby declare thatthe following is a full and exact description thereof, reference beinghad to the annexed drawings, making part ot' this specification, inwhichl Figure 1 is a perspective view. Fig. 2 is a section with part ot'the mill removed, showing` the interior. Fig. 3 is a perspective view ofa section of a sail.

The nature of our invention consists in opening the sections ofstationary sails of windwheels by centrifugal force and closing the sameby a spiral spring, thereby making our mill self-regulatin g, and alsomaking the frame or head with an opening through. the center, so thatthe pitman can pass through it into the standard or post with an openingthrough the center and be directly attached to a lever or .othermachinery.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construction and operation.

A is the platform which supports the post B. B is a post or standard,which has an openin g through the center for the purpose ot' allowingthe pitman K to pass through and be connected to the lever X.

Vis a frame or head, which supports the shaft J and the vane D andrevolves on the standard B by means of the lower portion being maderound and passing into the standard B and resting onthe projection atGr. J is the crank-shaft, which passes through the frame at I I andthrough the pitman K and revolves freely.

H is a hub, which is fast to the shaft J and supports the sails in theirproper position to be acted upon by the Wind.

C C C C C Q are movable sections, which are connected to the frames ofthe sails I I I l I I by pivots, as shown in Fig. 3, which allows themto revolve so as to present their edges to the wind.

a. a a a a a are rods, which are connected to the sections by pins orrivets passing through the ears d, as shown in Fig. 3, and then passingthrough the rods. The ears d are fast to the sections, which have apiece cut out at the center so as to allow them to open and notinterfere with the rods a a a a a a.

G is a cone or thimble which slides on the shaft J, and is connectedwith the rods a a a a a c by the wires S S S S S S. The wires S S S S SS can be straight, as in drawings, or can be attached to an elbow orright-angle lever workin g on a pivot'attached to the hub H. In thelatter case another rod or wire will be attached to the other end of theright-angle lever and to the sliding cone G.

U is a spiral spring, which presses against the cone G and keeps thesections closed by means oi' the wires S S S S S S or the rightanglelever-rods and rods a a a a a a.

E E E E E E are balls which are fast to the rods a a a aan., for thepurpose hereinafter to be described.

t t t are wires which are connected to the cone Gr and pass through thehub H, and are also connected to the slide m.

L is a lever which has a slot through it at I. There is a pin passesthrough this slot, and also through the projection which is fast to theframe V. The lever L can move up and down a trie, so as to allow the pinat O or the lever L to catch on the projection b. The lever is connectedto the slide m by means of prongs, which pass partly around and into agroove in the slide m. By moving this lever the sections C C C C C U canbe opened or closed, and thus the revolution of the windwheel entirelystopped or regulated by hand.

D is the vane which keeps the sails in their proper positions to beacted upon by the wind.

K is the pitman which operates the lever or pump. Itis connected to thelever Xby passing through a hole in the lever at Z. lt has a ange aboveand below the lever X, which allows it to vibrate the lever and alsorevolve. rfhere is a slot in the post B, so as to allow the lever X topass through and be connected to a pump or other machinery.

rEhe operation ot' the above-described machine is as follows: The windpressing against the sails causes them to revolve, thereby rotating theshaft J, which operates a pump or other machinery by means ot' thepitman K and lever X when the wind presses too hard on the sails andcauses them to revolve too fast. The balls or weights E E E E E E, bytheir centrifugal force, open the sections (l C O by pulling on the rodsa a a a a a. When the sections are open they allow the wind to passthrough between them, and consequently, the wind having less surface toact upon, the motion is retarded, so that the pressure of the spiralspring U is greater than the centrifugal force of the balls E E E E E E.It closes the sections C O C C C C by pressing against the cone Gr andpulling on the wires S S S S S S, which are connected to the cone Gr androds a a a a a. a, thereby closing the sails and giving the wind moresurface to act upon, inaking the machine self-regulating.

It is evident that instead ofthe spiral spring U upon the shaft J eacharm ofthe wind-wheel might be supplied with its own spring, actingindependently of but simultaneously with the other springs. It is alsoevident that'other means equivalent to spiral springs might be used forthis purpose.

We do not claim making Wind-Wheels having stationary sails with movableor revolving sections, as those have been long used; nor do We claim theapplication of centrifugal force to the regulation of windwlieels byhaving the same rotate or otherwise act upon movable sails; butI What Wedo claim as new, and desire to secure by Letters Patent, is

l. The balls E E, or their equivalents, attached to the movable sectionsof the stationary sails, in combination with the spring a, or itsequivalent, for the purpose of regulating the revolving motion ofwind-Wheels with stationary sails, the whole constructed and operatingsubstantially in the manner and for the purpose above described.

' 2. In an apparatus for utilizing the power of the Wind by means otWind-wheels, the pitman K, placed centrally in the post by which thewind-Wheel is supported, in combination with the lever X, workin gthrough an aperture in the said post, substantially in the manner andfor the purpose described.

3. In an apparatus for utilizing the power of the Wind bythe use of aWind-wheel, the

above-described mode of connecting the pitman K with the lever X-that isto say, by passing the pitman through the lever, and then, by means of ailange above and below the lever, enabling the Wind-wheel to revolvearound on its vertical shaft, and carrying' With it the pitman, withoutinterfering With the harmonious action of the machinery, substantiallyas above described.

4. In an apparatus for utilizing the power of the Wind by means of awind-Wheel, the combination of the lever L and the slide m, constructedand operating substantially in the manner andl for the purpose above setforth.
